There are two versions. Please can anyone explain the difference? I have Vista with an Intel dual core processor - any help telling me which to download would be gratefully received.

Got 64 bit Vista or 7? Use the amd64 download.Got 32 bit Vista or 7? Use the x86 download.

Thank you. I wish Microsoft could use english as well and just tell us which drivers are for which of their many OS systems. Would it really cost them that much for a simple explanation like you just provided. AMD sounds more like the chip maker rather than something else. Microsoft get with it. People like simple.

tried both versions on my win7 64 bit.... installation is aborted with an error message (no access to a certain registry entry.. and yes i have full admin rights on my PC).

i donÂ´t really need it but im curious if others have the same issue.

I have the same error. I tried the X86 version first, then the AMD64. I am wondering if my registery got messed up doing that. The key they refer to does not exist in my registry. I'll try it on a different pc later.
